Answer:
5
Step-by-step explanation:
let the number be a.
5a=25
divide both sides by 5
5a=25
5divide by 5a is a.
5divided by 25 is 5
therefore,a=5.
the number is 5

Answer:
Step-by-step explanation:
It is given that
By cofactor expansion across the first row, we get
![\Delta=3\left[(-1)^{1+1}\begin{vmatrix}3&3\\4&-2\end{vmatrix}\right]+0\left[(-1)^{1+2}\begin{vmatrix}2&3\\0&-2\end{vmatrix}\right]+3\left[(-1)^{1+3}\begin{vmatrix}2&3\\0&4\end{vmatrix}\right]](https://tex.z-dn.net/?f=%5CDelta%3D3%5Cleft%5B%28-1%29%5E%7B1%2B1%7D%5Cbegin%7Bvmatrix%7D3%263%5C%5C4%26-2%5Cend%7Bvmatrix%7D%5Cright%5D%2B0%5Cleft%5B%28-1%29%5E%7B1%2B2%7D%5Cbegin%7Bvmatrix%7D2%263%5C%5C0%26-2%5Cend%7Bvmatrix%7D%5Cright%5D%2B3%5Cleft%5B%28-1%29%5E%7B1%2B3%7D%5Cbegin%7Bvmatrix%7D2%263%5C%5C0%264%5Cend%7Bvmatrix%7D%5Cright%5D)
![\Delta=3\left[-18\right]+0\left[(-1)(-4)\right]+3\left[8\right]](https://tex.z-dn.net/?f=%5CDelta%3D3%5Cleft%5B-18%5Cright%5D%2B0%5Cleft%5B%28-1%29%28-4%29%5Cright%5D%2B3%5Cleft%5B8%5Cright%5D)
Therefore, the value of determinant is -30.
By cofactor expansion across the second column, we get
![\Delta=0\left[(-1)^{2+1}\begin{vmatrix}2&3\\0&-2\end{vmatrix}\right]+3\left[(-1)^{2+2}\begin{vmatrix}3&3\\0&-2\end{vmatrix}\right]+4\left[(-1)^{3+2}\begin{vmatrix}3&3\\2&3\end{vmatrix}\right]](https://tex.z-dn.net/?f=%5CDelta%3D0%5Cleft%5B%28-1%29%5E%7B2%2B1%7D%5Cbegin%7Bvmatrix%7D2%263%5C%5C0%26-2%5Cend%7Bvmatrix%7D%5Cright%5D%2B3%5Cleft%5B%28-1%29%5E%7B2%2B2%7D%5Cbegin%7Bvmatrix%7D3%263%5C%5C0%26-2%5Cend%7Bvmatrix%7D%5Cright%5D%2B4%5Cleft%5B%28-1%29%5E%7B3%2B2%7D%5Cbegin%7Bvmatrix%7D3%263%5C%5C2%263%5Cend%7Bvmatrix%7D%5Cright%5D)
![\Delta=0\left[(-1)(-4)\right]+3\left[(-6)\right]+4\left[(-1)3\right]](https://tex.z-dn.net/?f=%5CDelta%3D0%5Cleft%5B%28-1%29%28-4%29%5Cright%5D%2B3%5Cleft%5B%28-6%29%5Cright%5D%2B4%5Cleft%5B%28-1%293%5Cright%5D)
Therefore, the value of determinant is -30.
